In comparison to the rotation of the Earth, the movement of the Earth around the Sun makes us go faster in space! With a radius of just over 6,000 kilometers, the rotational speed of the Earth's surface is not very fast. Even if we stand at the equator, the speed is approximately only 0.5 kilometers per second. However, since the Earth is about 150 million kilometers away from the sun, the speed of the Earth's orbiting movement is much faster. It can reach up to 30 kilometers per second. In comparison, airplanes can only fly at a speed of 0.3 kilometers per second!
